Description

The Rotameter 5–25 m³/h plastic tube type flow meter is an in-line variable-area flow meter designed for measuring and monitoring the flow rate of water through a piping system. The visible float moves within the graduated measuring tube as water passes through the meter, allowing the operator to read the approximate flow rate directly from the scale.

Its plastic tube construction and easy-to-read graduated scale provide a simple visual solution for monitoring high water-flow rates in filtration, water purification, reverse osmosis and other water-treatment applications. The mechanical design requires no electrical power for basic flow measurement, making the rotameter suitable for commercial and industrial water-treatment systems.

How a Rotameter works:

A Rotameter is a variable-area flow meter. As water flows upward through the measuring tube, it causes the internal float to rise. The position of the float corresponds to the water flow rate shown on the graduated scale.

As the flow rate increases, the float rises to a higher position within the measuring tube. The operator can then read the approximate water flow rate directly from the graduated scale.

This provides a simple visual indication of water flow without requiring electrical power.

Installation:

The Rotameter should be installed in accordance with the manufacturer’s installation requirements, with the measuring tube positioned in the correct orientation to allow the float to move freely and provide a clear flow-rate reading.

The connected pipework should be properly supported to prevent excessive mechanical stress on the meter. Flush the pipework before installation to remove debris that could interfere with the float or measuring tube.

Ensure that the system flow falls within the Rotameter’s 5–25 m³/h measuring range and that the operating pressure and temperature remain within the specified limits.

Important:

• Check that the required system flow falls within the 5–25 m³/h measuring range.
• The equivalent flow range is approximately 83.3–416.7 L/min.
• The equivalent flow range is approximately 5,000–25,000 L/h.
• Confirm that the 75 mm female connection is compatible with the existing piping system.
• Ensure that the system operating pressure does not exceed 6 bar.
• Ensure that the operating temperature does not exceed 60°C.
• Install the Rotameter in the correct orientation to allow the float to move freely.
• Flush the pipework before installation to remove debris.
• Support connected pipework to prevent excessive mechanical stress on the rotameter.
